Laravel 4.1 Why is CSRF protection not working after upgrade?

Question

Laravel

Updated from 4.0.3 to 4.1.
And after that the csrf filter started to issue token mismatch. Although I check that the token is in the form, the filter receives it. But the session already has another token.
It changes even before the filter is triggered.
Route is correct.

Route::post('login', array(
            'before' => 'csrf',
            'uses' => '[email protected]'
        )
    );

Answer 1

and what are the settings in session.php?

'lifetime' => 120,

'expire_on_close' => false,

Did you update according to the instructions?
